piRNA-Guided Genome Defense: From Biogenesis to Silencing

Annual Review of Genetics, 2018
PIWI-interacting RNAs (piRNAs) and their associated PIWI clade Argonaute proteins constitute the core of the piRNA pathway. In gonadal cells, this conserved pathway is crucial for genome defense, and its main function is to silence transposable elements. This is achieved through posttranscriptional and transcriptional gene silencing.

Post-transcriptional gene-silencing: RNAs on the attack or on the defense?

BioEssays, 2000
Post-transcriptional gene-silencing (PTGS) was first discovered in plants and results from the sequence-specific degradation of RNA. Degradation can be activated by introducing transgenes, RNA viruses or DNA sequences that are homologous to expressed genes. A similar RNA degradation mechanism which is inducible by double-stranded RNA (dsRNAs), has been

Silencing the Jasmonate Cascade: Induced Plant Defenses and Insect Populations

Science, 2004
We transformed the native tobacco, Nicotiana attenuata , to silence its lipoxygenase, hydroperoxide lyase, and allene oxide synthase genes in order to inhibit oxylipin signaling, known to mediate the plant's direct and indirect defenses.

How to Silence One’s Conscience: Cognitive Defenses Against the Feeling of Guilt

Journal for the Theory of Social Behaviour, 1998
This work presents an analysis of the feeling of guilt and in particular of the cognitive defenses against it. It shows how the need to avoid or mitigate the feeling, with the suffering implied, affects the perception and judgment of oneself and others.

Plant viruses against RNA silencing-based defenses: Strategies and solutions

2020
Plants defend themselves from pathogenic virus infections by deploying a complex defense system. Fundamental in the plant antiviral immune system is the RNA silencing (RS) pathway, which consists in a multilayered set of enzymatic components. The RS machinery targets the double-stranded RNA, generating 21-24 nucleotides (nt) small interfering RNAs ...

Homology-dependent gene silencing and host defense in plants.

Advances in genetics, 2002
Analyses of transgene silencing phenomena in plants and other organisms have revealed the existence of epigenetic silencing mechanisms that are based on recognition of nucleic acid sequence homology at either the DNA or RNA level. Common triggers of homology-dependent gene silencing include inverted DNA repeats and double-stranded RNA, a versatile ...

Imagined Interactions With the Boss: Upward Dissent and Defensive Silence in Organizations

Management Communication Quarterly
Imagined interactions (IIs) are conversational daydreams communicators can use to envision how interactions might unfold prospectively or how they might have unfolded differently in retrospect. In this study, imagined interactions with the boss (IIB) were investigated alongside employees’ upward dissent and silence.

Supervisor Incivility and Employee Defensive Silence: The Role of Depersonalization as Mediator

Social Science Review Archives
This study investigates the intricate relationships between supervisor incivility and employee silence, focusing on the mediating role of depersonalization. Drawing on Conservation of Resource (COR) theory, the research examines how low-intensity deviant behaviors from supervisors undermine employees' psychological resources, leading to defensive ...
